Behaviour Biology A2 - Module 4

I made this presentation for school and i thought id share it , sorry the pictures may not be relavent its because i couldnt be bothered to find some interesting photos for the slides , but i hope this helps a few idividuals and find it useful

Slides in this set

Slide 1

Module 4 - BehaviourBEHAVIOUR ­ IS THE RESPONSE OF AN ORGANISM TO ITS ENVIRONMENT WHICH INCREASES ITS CHANCE OF SURVIVAL.…read more

Slide 2

Innate behaviour Innate behaviour is natural and instinctive hence it is genetically inherited and organisms of the same species have similar behaviour (stereotypical). You cannot change or alter innate behaviour. The organism is unconscious of innate behaviour. The behaviour is not needed to be learned . An example of innate behaviour ; woodlice moving away from the sun to under a rock to hide from predators.…read more

Slide 3

The types of innate behaviour Advantage of innate behaviour is that it allows the organism to react quickly to certain stimulus. Escape reflexes ­ an organism moves away from potential danger. Taxses (tactical response) ­the organism move towards or away from a directional stimulus . Kenisis ­ when the rate of movement increases due to the organism being in unfavourable conditions .…read more

Slide 4

Learned behaviour Learned behaviour is influenced by the environment , it allows animals to respond to change in the conditions an example would be learning to avoid harmful food. Habituation Operant conditioning Classical conditioning Latent learning Insight learning…read more

Slide 5

Habituation The animal learns to ignore certain stimuli because of repeated exposure to the stimuli which results in no reward or punishment. An example of habituation is people sleeping while living by a rail way station . By ignoring harmless stimuli you save time and energy.…read more

Slide 6

Classical conditioning Is when a natural response which is unconditioned is then associated with a condition response. ·An example is `Pavlovs dog' experiment where a scientist trained a dog to salivate when hearing a bell ring. ·When food (unconditioned stimulus) was presented to the dog the dog salivated (natural response) ·So when Pavlov rang the bell first time towards the dog there was no response . ·When Pavlov rang the bell and then rewarded the dog with the food the dog recognised that the bell which was the unconditioned stimulus is associated with food . ·In the future when Pavlov rang the bell the dog salivated because the bell/ringing has now become a condition response and is automatic hearing that particular stimulus.…read more
